coivrrivarrori'anenn TABLE.' y Y '1) To ZZ whom t may concern:

Be it known that l, BnNNY M. Swanson, a citizen of the United States, vresiding at Los Angeles, inthe county of LoS-Angeles :and useful Improvement-s Vin Combination .Angle Tables, of Whichthe following," is a specification. i V

.supporting structures and more particularly to an adjustable angle table. that is adapted to -be positioned on the bed kplate or table of a shaper or like machine for engagingV and supporting Work that is to have an an- ,gularfsurfaceor cut made upon its upper face, or in which holesare to be drilled at predetermined angles. A

The principal objects of my invention are to generally improve upon and simplify the construction of the existing types of similar Work holding devices, to provide a de.- vice that is relatively simple in structure, capable of being easily and cheaply produced, readily manipulated'when adjusting the. engaged Work, and further, to provide an angularly adjustable Work holder that will be very effective in performing its intended functions. Y

lith the foregoing and other objects in view, my invention consists in certainno'vel features of construction andr arrangement of parts that'tvill be hereinafter more fully described and claimed.. and illustrated in the accompanying drawings, which shovvsioneV specic embodiment, in which:

Fig. l is a top plan view of an angularly adjustable Work holding bloc-lr or table of my improved construction with parts thereof broken aivay and in section, in order to more. clearly illustrate theY construction of the device.

loiverportion thereof terminating in a flange l ll. that is adapted to rest directly upon and besecuredfto the tableor-bedplateylof j Y a Shaper or like machine., and State of California, have invented new ln order that the vdisc or base member l() may be adjustably positioned on theA table Y l2, the base flange llmay be provided with "60 arcuate slots such'as lla` andivhich receive l boltsv 12a, the latter passing through theA shaper table and being retained therein by Formed in the upper portion of the body l() of thebase member is an annular groove V13 that is inclined With respect to a hori- Zontal plane, and the ilange lll-or that lportion ofvthe body immediately above said inclined annular groove, and which is slight- Y ly smaller in diameterV than theA diameter of the main body portion of the base member 10, `has an inclined upper surface 15 that vis parallel with the inclined annular groove 13. The upper member of the device comprises a disc-like body l'the diameter of which equals the diameter -of body 10, and formed integral Withthe vupper portion of said body 16.v is a flangel? the diameter of which is substantially equal tofthe* diameter of base flange llof the lower member, Y Formed in the loWe-r portion of the body 16 is an annulargroove 18 which, When the parts of the-device are in theirnorm'al positions, occupies an inclined plane that is op'- vpositely arranged with respect to the plane said inclined groove 18, constitutes aV flange 19 the underface 20 of which is Vinclined'fso that vit occupies a plane parallel vvith that occupied by'said 'groove 18. I i

In thel form shown, the upper membe'rgof the device comprises also a WorkI receiving or Work supporting surface 23,"shoivn as separate from the block 16. In the embodiment shown I'have formed in ilange 17 a pair of oppositely arrangedV arcuate slots 21, and passing therethrough and through Ysuitably located apertures in a work supporting plate or table '23 are bolts 24, the 'upper ends thereof'carrying nuts25 thatv occupy countersunk recesses 26 that are formed -in the top of the plate or'tableY 23. By virtuev of the construction y'just described,- the Work receiving pl'atejo'r table 23 '410;and 16 is a disc 29^having inclined upper and lower faces that are adapted Yto bear against'l the correspondingly kinclined faces V2OlandM-15 on blocks 16 and 10,:said interposed discbeing formed in mating halves in erderto facilitate the assembling or tak-ing vlapart ofthe device,andthe line ofv division A between them-ating parts beingdisposed so that portions 30 of the parts of said interposed 1disco verlapor extend pasteach other vat the centerof the device.

VYFormed integral with the marginal portion .of disc V29 and on the top fand bottom thereof, are ianges31 that overlie the Vflanges 14 andr 19 on the bodies 16 and 10and extending inwardly from the outer portions of these flanges 31, are annular flanges that occupyI inclinedplanes corresponding to the planes occupied by the upper and lower faces .ofthe interposed. disc 429, and said :annular flanges occupy the grooves 13 and 18 that areformed in discsl() and 16. (See Fig. 3.)

4Formed in the edge of the disc. 29 and in alinement with the overlapping portions 30 of the parts: of said disc, is a substantially rectangular recess 33 in which is arranged a block 34, and said block is provided on its inner face with substantially rectangular notches 35 that are adapted tore- .Ceive the iianges 14 and 19 on-thediscs10 and 16.

Passing through alined apertures formed in block 34,*the parts of disc 29 and the overlapping inner portions 30 of said parts, is a rod 36 one .end of which is screwseated in the edge portion of the interposed disc 29, at a point diametr-ieally opposite said block 34. f Y

The end portion of thisirod thatprojeets' outwardly from the block 34'receives a tubular member 37, and `which latter is locked on the projecting portion ofthe rod by a nute38 that is mounted onithe threaded end portion of said rod.

1By tightening this Anut 38, Vthe tubular member or sleeve 37 bears againstithe outer surface ofblock BAeand causes the same-.to bear against the ,anges 111 `:and 19fof the members 10y and Y 16, thereby vvefectiufely lock ing thelatter against relative rotary move` ment after the member `16 lmsibeen` adjusted to an angular position relative to the lower or base member. c

Y 1n the use of my improved work support ing block, thework that 4isto be provided withY an l:inclined cut in itsk upper `face or which is to be drilled to form inclined or angular holes, is= positioned on top of disc 23 and'firmly clamped thereupon by the bolts 28 vor clamping members carried thereby, after which the nut 38 is unscrewed in order i to relieve theiclam-ping pressure of the inner end of sleeve 37 against block 38 and consequently permittingthe `intermediate disc` 29 to be freely rotated .uponi the lower member 10,*an'd likewise to permitl theupper :member vit-toy be independently rotated upon ldisc 29.

:By x manuallyV engaging sleeve 37, iiwvhi'ch :perfoms the `function ofa handlefintermediate `disc 29 can-'be rotated in either direction upon base member 10, thereby -changfing the-positionofthe angularplane occupied kby the top of said intermediate rdisc and ycorrespondingly zchanging :the

`.angular plane occupied'byithe -top'of upperl memberA 161and thefwork Ycarrying"plate 23 which action,Y through A sleeve 37,; clamps the f block 34 .againstithe V'flanges A111 and 19 of members .10 f and 116,;and also vclamps the intermediate disc against rotation :by Y'the arrangement of said block .34'within Athe recess 33. f

Thus, `,the upper surface 'of 'the work 4is positioned in a true horizontal plane tand in such; position said work may be vengaged by the tool ofthe `shaper ormachinenupon -which :the device is fpositioned, and when said work is removed from the'h'olcler, the cut or-surface engaged by theitool willhave the desired angle relativeto that portion of thew-ork that was positioned directly :against Athe-upper surface of 'disc23- Y In order 4to laccurately f determine :the l ydegree of adjustment imparted to the member 156` and the -workfsupporting'disc or table carried-thereby, suitable zguide marks fmay be located v:at corresponding vpointson .the peripheral surfaces .of the :bodies 'of @the members 10 v.and'16 and a suitable graduated scale may tbe .arranged on ithe peripheral surface tof disc 129, :and by :observing l"the positions of 1the 4gra'du.fa-.tions `on the .intermediate disc with :respectto the fixed marks on the -members `101-and Y 16,19. very Vaccmjate adjustment of the work =carrying :member can 'fhe accomplished.

A work supporting table or block of my improved construction is comparatively simple, is capable ofv being easily and cheaply produced, may be advantageously Vused wherever certain pieces of work require the formation of angular cuts or faces, or the boring of holes at `predetermined angles, and said device is capable of ready adjustment and is very effective in perfoming its intended functions.

It will be readily understood that minor changes in the size, form,V number and construction of the various parts of my improved worlr supporting block or table may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forthlin the appended claims.
